Chapter I INTRODUCTION Background of the Study The internet is a global system of interconnected computers. It is a vast collection of networks all in one package. It is a source of almost limitless information that we utilize in the everyday things we do. Internet today is not considered as a luxury but a necessity to people. People use internet for different purposes such as e-mailing, researching, gaming, business and transaction activities, and others. (Retrieved from http://www.webopedia.com/TERM/I/Internet.html) Wifi known as Wireless Fidelity, is widely known as wireless networking technology that uses radio waves to provide wireless internet access. It has provided us with a simple yet convenient way of connecting to the internet via wireless method. Wifi has removed the use of internet cables in connecting to the internet. Unlike cables, wifi routers use radio waves to send information back and forth from the router to the computer and vice-versa. This process repeats itself over and over again. Rather it has provided an easier way to connect to the internet via Wi-fi routers. It has enabled people to connect to the internet at different places: whether in the house, the office, at Wifi routers present a more flexible and independent way of connecting to the internet, school, and others. (Davis, 2004) A wireless Signal Booster is a tool that maximizes one’s network signal throughout any room in the house resulting to a fast and reliable Internet access for multiple users at once. It provides a reasonable and low-cost alternative to upgrading your router. The emergence of Wi-fi booster came from the idea that Wi-fi range has limits. Because most wi-fi standards can only give access range from 50 to 100 meters, Wi-fi boosters have been developed to increase the range. Wi-fi boosters work just like a radio or a television antenna. Antennas reflect radio waves from the transmitter to the receiver, thus signal is amplified. (Retrieved from www.countrymilewifi.com/what_is_wifi.aspx) Cantennas and other forms of homemade wi-fi booster have been created to address problems of poor Wi-fi signals. These homemade wi-fi signal boosters are usually metallic- made of sheets copper, aluminum, steel, etc. this is because metals tend to reflect radio waves more than any other material. (Retrieved from http://www.qsl.net/va3iul/) Nowadays, wireless internet is becoming popular technology to people worldwide. The ease and comfort of use of this technology lies with speed and accessibility. However, in this present day economic downfall, some people tend to bypass poor signal connection or choose not to buy commercial wi-fi boosters or upgrade routers as it would add up to financial burden. The proponents chose to do the study for the reason that in doing so, wireless internet users may be able to address poor wi-fi signal using cost-effective method aside from other conventional homemade
boosters. This will give wi-fi router users another practical option (soda can) that is readily available in almost everywhere. It will provide the study a good alternative to previous material used for homemade wi-fi boosters. Objectives of the Study General Objective: To determine the effectivity of aluminum soda cans in amplifying wi-fi network signals as an alternative to other commercial wi-fi boosters. Specific Objectives: Specifically, this study aims to: 1. To construct wi-fi booster using soda can 2. To determine the effectivity of aluminum in amplifying wi-fi signals 3. To compare the strength of wi-fi signals in each of the different set-ups. Significance of the Study Society. People in the society will benefit from this study because wi-fi boosters give solution to wi-fi signal problems providing people with ease of use thus making use of internet and communication among people hassle-free. Economics. With the economic setback that the country is experiencing, people become more practical and economical in their financial expenditures. When a wi-fi user encounters problems regarding poor signal, there maybe no other option but to leave the matter unresolved rather than to spend money for commercial wi-fi booster or for router upgrade. With this homemade solution, wi-fi router users are provided with lowcost yet equally effective technological product. Environment. Pollution is one of the greatest threat to our environment. One major cause of pollution is poor waste management. To lessen this problem, recycling materials is done so as to downsize garbage volume. Recycling soda can as wi-fi booster can help our environment. Technology. Wireless networking is an important breakthrough in computer and communication technology. This technology has brought our world to several Wi-fi advancements of today. The ideas from this project may take the same path. Through the ideas presented in this research, advancement and improvisation may be done in the future, contributing to a more conventional and modern homemade wi-fi technology. Education. Internet has become a part of the major tools that assist students in facing demanding challenges of education today. With the evolution of Wi-fi technology and the overwhelming use of this technology in homes and most establishments, students can research with ease and convenience almost everywhere. But problems like poor wi-fi signal can limit student;s productivity in research works. This research
educates them about alternative solution in amplifying wi-fi signals so they can maximize time and effort in doing research works.
Chapter II REVIEW OF RELATED LITERATURE AND STUDIES
Related Literature The Internet is a global network connecting millions of computers. More than 100 countries are linked into exchanges f data, news, and opinions. The Internet is decentralized by design. Each internet computer, called the host, is independent. Its operators can choose which Internet services to use and which local services to make available to the global Internet community. Remarkably, this anarchy by design works exceedingly well. There are varieties of ways to access the Internet. Most online services offer access to some Internet services. It is also possible to gain access through a commercial Internet Service Provider (ISP). No one actually owns the Internet, and no single person or organization controls the Internet in its entirety. The Internet is more of a concept than an actual tangible entity, and it relies on a physical infrastructure that connects networks to other networks. (Retrieved from http://www.webopedia.com/TERM/I/Internet.html) Wi-fi, short for Wireless Fidelity, is a widely known wireless networking technology that uses radio waves to provide wireless access the Internet. It refers to any system that uses 802.11 standards. Wireless router or similar device creates area in which appropriate devices can connect wirelessly to a network or gain Internet access. Connecting to the Internet through wi-fi involves wi-fi device (the client), wi-fi broadcast unit (the access point), network connectivity hardware (such as a router or modem), and actual Internet connection (usually via cable or DSL. (Davis, 2004) A device called a wireless transmitter receives information from the Internet via your broadband connection. The transmitter converts the information into a radio signal and sends it. The whole process, meanwhile, works in reverse, with the computer sending information to the wireless transmitter. It then converts them and sends them via broadband connection (Retrieved from http://www.bbc.co.uk/webwise/guides/about-wifi). Different versions of 802.11 standard have been released over the years. Wi-fi products are identified as 802.11 and are further identified by a lower case letter that identifies which specific technology is in operation. Wi-fi products have three more technologies – Wireless B/802.11b, Wireless G/802.11g, and the latest which has the widest range – Wireless N/802.11 (Retrieved from www.wifi.org/discover-and-learn). All wi-fi standars except Wirless N/802.11n, has typical indoor range of about 100 feet and very slightly in outdoor range from 300400 feet. Wireless N/802.11n has a typical 200 feet indoor and outdoor range of about 800 feet (Retrieved from www.countrymilewifi.com/what_is_wifi.aspx). A wireless Signal Booster can extend you network signal throughout any room in your home, giving your entire family fast and reliable Internet access for multiple users at once. It also provides an affordable alternative to upgrading your router. A Wi-fi signal amplifier (sometimes called “signal booster”) attaches to a router, access point of Wi-fi client at the place where the antenna connects. Bi-directional antennas amplify the wireless signal in both transmit and receive directions. These should be used as Wi-Fi transmissions are two-
way radio communications. (Retrieved from http://compnetworking.about.com/od/wirelessfaqs/f/extendwifirange.htm) If you are experiencing data transmission issues, you can always add a wi-fi signal amplifier. Often called a signal booster, this device connects to your wireless router or wi-fi client where your antenna attaches – and increases signal reception. Wif-fi transmission amps can also enhance the download and upload speed, making your connection faster and guaranteeing that you never drop transmission. (Retrieved from http://voices.yahoo.com/tips-boosting-wireless-router-signal-11029790.html) The use of homemade boosters is becoming popular because it is cheaper and costeffective. The idea of these homemade boosters may have evolved from the idea of transmitting of radio waves using antennas. Metals are typically used as material for antenna because metals reflect signals. (Retrieved from http://www.qsl.net.va3iul/) Smooth metal surfaces of good electrical conductivity are efficient reflectors of radio waves. Metals like steel, silver, aluminum, and copper are common example. Several homemade wi-fi boosters were being used now such as wi-fi boosters made from metallic kitchen sieves. Pringles container and coffee cans are also used as homemade wi-fi boosters. They are popularly known as cantennas because they are built out of tin cans. 34.5 ounce coffee cans work better than Pringles container in amplifying signals. (Gralla, 2005) All of these homemade wi-fi boosters has metallic features that can increase the range of signal (Retrieved from http://voip-sol.com/10-ways-to-boost-your-wifi-signal/).
Related Studies Klanac (2004) made an exploratory study of the roles of internet communication in business relationships. The analysis of the study shows that the most emphasized role of the Internet is information exchange role. Maheswarappa and Emmaunel (2003) identified an exploratory study at Gulbarga City, showing a high rate of computer knowledge. Mehajan (2006) conducted a study on internet use by researchers in Punjab University, Chandigrah, which analyzed how the convergence of information and communication technologies, as embodied by the Internet has transformed the present day society into a knowledge society. Chandran (2000) carried out a study on the use of internet resources and services in S.V. University, Tirupati, indicating that more than 56 percent of respondents used to the Internet to access information. Kaur (2000) studied Guru Nanak Dev University, and Bavakutty and Salih (1999) conducted a survey at Calicut University, which showed that students, research scholars, and faculty members used the Internet on education and research purpose. Also in a study conducted by Nie and Erbring (2000, the found out that 43% of American household are connected to the Internet and that 55% of population has access to the internet. Part of the study also gave the information that E-mail is by far the most common internet activity with 90% of all Internet users from their respondents claiming to be Emailers.
Kadu and Gulhane (2011) studied existing technology and also methodology employed in wi-fi antenna boosters. According to the study, wireless signals are susceptible to a lot of data loss. Whe it comes to the wireless signal strength that will be received, the topography of the place where we stay is a declining factor. They found out that wi-fi signal boosters increase the strength of transmitted, as well as received signals by 600%. On another research conducted by Kadu (2012) about testing the effectivity of manually designed Wi-fi cantenna, the study gave a conclusion that Wi-fi booster cantenna is used in improving the signal strength and is basically effective in locations where there is coverage problem in case of mobile or when the signal strength becomes less as the distance increases. An experiment made by Alfa (2008) in which Pringles can was used as a material for cantenna, he found out that a parabolic antenna with 180 degree doubles the signal gain wifi and lessended signal noised due to interference.
